which Ashall yet be compact in size and con.

venient to carry in the pocket.

A further object of my invention is to provide a tobacco-pipe in which the smoke can be separatedfrom the nicotine which contains the injurious` principle of tobacco.

My invention therefore resides in the novel construction, combination, and arrangement of parts hereinafter fully specified, kand particularly pointed out in the claims. I

In the accompanying drawings, Figure l is a side elevation of my improved pipe.' Fig. 2 is a side elevationfof the several Vparts of the pipe separated froml each other, and Fig.`

3 is a longitudinal central section of the pipe.

Referring to the drawings, I represents the bowl of the tobacco-pipe, having a tapering lower en'd 2, which tits tightly into the conical'end 3 of a slightly-tapering or conical' stem 4. Said stem is hollow, as shown atr,

and into the cavity 5 the smoke is drawn from the bowl I through the smalllnozzle 6. The smoke passes out from the cavity 5 through an opening 7 in the top of the stem, said opening discharging into a deep yspiral groove 8, cut on the outside of said stem almost the eutire length thereof to the other end of the stem. The smoke is confined in said groove by means of a casing 9, slightly tapering or conical to conform to`theshape of the stem and iitting tightly upon the threads of the stem betweenV the grooves. The smoke is y thus compelled to pass in a spiral or tortuous circuit, and thus to travela considerable dis` tance to the smaller end of the stem, where it vpasses through anopeninglO into a conduit-ll ling the smoke to pass from said cavity along the spiral groove. Y

I preferably make the inner or smaller end ofthe casing I0 with a thin edge, as shown at 14, so that said casing may be slipped off from the threads of the stem over the mouthpiece without unscrewing said mouthpiece.

An important feature of my invention is the provision whichis made for the' separation of the nicotine Afrom the smoke. I do this by providing ajcavity 5, into which the smoke and nicotine are discharged, and 4providing a single outlet only from said cavity and that at the top of the cavity. By this means no nicotine will be drawn up through said outlet until the cavity is substantially full to the top. I am aware that it has been proposed to construct a pipe having a plurality of passages on the outside of the stem of the pipe, said passages being closed by an exterior casing and the interior of said stem being hollow ateach end to form cavities; butin all former constructions, so far as I am aware, the cavity near the bowl has not been completely closed to any exit therefrom except lthrough the top. The consequence was that the nicotine'very quickly 'filled the cavity to such an extent as to be drawn through the outlet or outlets in the lower lpart of the cavity andy was carried along the In my invenexternal groove or channel. tionthis objection is avoided.

Another advantage follows in that by havin g a single deep groove or channel instead of a plurality of shallow grooves the pipe can be made quite short', as short as the ordinary tobacco-pipe, although the distance traveled by the smoke is very considerable.

Anotherimportant feature of my invention consists in the construction of the stem, hollow or open from one end to the other and closed at the inner end by the mouthpiece. This permits of the pipe being very quickly cleaned and freed from nicotine. The stem beingopen at both ends when removed from thev mouthpiece and bowl may be washed and thoroughly cleaned with the greatest ease.

I claimvI.V A tobacco-pipe having a bowl, a detachable stem spil-ally grooved on the outside, a casing'inclosing said groove, and a mouthlmouthpiece closes the cavity y5, thus compel- IOO `)ieee said stein bein(Y hollow and/unobstructed throughout its length, whereby, when detached, its interior may be readily cleansed,

and fitting onto the bowl at one end and having its cavity closed by the mouthpiece at the other end when the latter is in positionsaid` able stein spirally grooved on the outside, a casing inclosing said groove, and a mouth piece, said groove connecting with a duct from the bowl and with a passage through the mouthpiece, said stem being hollow and unobstructed throughout its length, whereby,

whendetached, its interior may be readily cleansed, and fitting onto the bowl at one end and having its cavity closed by the mouth- .piece at the other end when the latter is in position, and said casing being removable from thefstem over the `mouthpiece when the latterisn position, whereby said groove may be cleansed without removing said mouthpiece,substantially as described.

In witness whereof I have hereunto set xny hand in the presence of two subscribing wit- WILLIAM R. HALE. Witnesses:
